If 2.3g of the same gas is added to this constant 5.25L volume and the temperature raised to 68 degrees Celsius, what is the new gas pressure?

**DrBob222**, Tuesday, January 18, 2011 at 10:11pmUse PV = nRT and solve for n (from the first 10.8 g sample). Then

moles = n = grams/molar mass.

You know N and g, solve for molar mass.

Then convert 2.3 g to moles (moles = grams/molar mass), add to moles at the beginning, and use PV = nRT again to solve for P.
